Was crawling around under my '21 Freewheeler this evening and was concerned that the oil cooler fan didn't spin free by hand. I'm used to checking computer cooling fans by a quick flick of a finger to make sure they're spinning freely. Found out if you turn the ignition switches on without starting and go full throttle for a few seconds the fan will start. Can't miss it and man does it move some air. Just posting in case a passing lurker may not know this.
